Incoming mail (POP3, IMAP) server: Login to the web-based mail interface which will be at a URL of the form http://webmail.yourdomainname.com and go to Settings >> Forwarding and POP/IMAP settings to get this information.

The following window will display the success message - Congratulations, you have successfully entered all of the information required to set up your account. To save these settings, click Finish.

Open the Internet Accounts dialog box referring to steps 1 and 2. In the Mail view, you will see the Account you have just added. Now you need to click Properties.

Under the Servers tab, you need to check the checkbox My server requires authentication placed under Outgoing Mail Server. Once this is done, click Apply.

IMPORTANT Usually, the port used for the Outgoing Mail Server/SMTP Service is 25. However, there might be a situation where your ISP might be blocking the use of port 25 for SMTP service. Many ISPs block port 25 in order to minimize the amount of spam sent using their network. If you are facing issues sending mails using the default port 25, you can confirm with your ISP whether port 25 is indeed blocked by them. To circumvent this, you can use an alternate port 587 for sending mails if port 25 is blocked. Here's how:

a) In Outlook Express, on the Tools menu, click Accounts b) Select the email account you wish to modify and click Properties c) Under the Advanced tab, replace the default port number 25 with the alternate port number 587 in the field provided for Outgoing mail (SMTP) d) Click OK and then Close to save the changes

Your setup is complete. When you click on the Send/Receive button, your email will be downloaded by Outlook Express.
